embodiment of the invention is the accompanying drawing, in

Fig. 4 is a fragmentary view in section on a I vertically disposed rearwardly projecting wing-like side plates 5 having outturned flanges 5 at their forward ends. The gate 1 is shaped to swing between the side plates 5 and in the embodiment illustrated has a forwardly projecting segmental flange-like top portion 8 The pivot member 9 has pivot portions in at its ends provided with knife-like pivot edges H. The side plates 5 have elongated horizontal openings 12 therein through which the pivots project.

of the bearing receiving slots while the bearing retaining H of the pivots 18.

The gate is provided with an like weight 20 which is mounted on the screw ii for swingin adjustment in 28 and 29.

When the regulator tal flue, as is illustrated, the link 34 should be When the gate swings outwardly as the result of a downdraft, indicated by. dotted lines in Fig, 1, the auxiliary weight is supported by the chain 35 connected to the bracket 35 on the housing.

The numeral 31 represents a thermal switch which is in the path of the outflowing gases as is illustrated in Fig. 1 and operatively associated with a burner control valve. Claims to this portion of my invention are, however, in my application 237,855.

I have illustrated and described my invention in a highly practical embodiment thereof. I have no attempted to illustrate or describe other embodiments or adaptations as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired.

Having thus described claim as new and desire Patent is:

1. In a barometric draft regulator, an open ended gate housing, a pivotally mounted control gate disposed in said housing for opening inwardly during an updraft and outwardly during an outdraft, said gate being disposed approximately vertical when closed, weighting means on said gate, the center of gravity of the gate and weighting means thereon being disposed vertically below the pivotal axis of the gate to effect a closing torque on the gate, an arm mounted on and projecting outwardly from said gate, said arm having a downwardly projecting outer portion with vertically spaced holes therein, a bracket projecting forwardly from said housing, an auxiliary weight for producing additional closing torque on the gate when the gate opens inwardly due to an porting element connecting said auxiliary weight to said arm and selectively engageable with said holes therein, and a flexible second supporting element connected to said auxiliary weight and to said bracket and of such length as to support the auxiliary weight when the gate opens outwardly due to an outdraft.

2. In a barometric draft regulator, an open ended gate housing, a pivotally mounted control gate disposed in said housing for opening inwardly during an updraft and outwardly during an outdraft, said gate being disposed in an approximately vertical plane when closed, weighting means on said gate disposed to efiect a closing torque on the gate, an arm mounted on and projecting outwardly from said gate, a bracket projecting forwardly from said housing, an auxiliary weight for producing additional closing torque on the gate when the gate from said closed position opens inwardly due to an updraft, a first weight supporting element connecting said auxiliary weight to said arm, the connection of said supporting elment to said arm being horizontally spaced from the plane of the gate, and a flexible second supporting element connected to said auxiliary weight and to said bracket and of such length as to support the auxiliary weight when the gate from said closed position opens outwardly due to an outdraft.

3. In a barometric draft regulator and burner control, an open ended gate housing, a pivotally mounted control gate disposed in said housing my invention, what I to secure by Letters updraft, a first weight sup- 1 gate to project through said openings in for opening inwardly during an updraft and outwardly during an outdraft, weighting means on said gate ac ing to effect a closing torque thereon, an auxiliary weight for producing additional closing torque on gate from said closed position opens inwardly due to an updraft, a first weight supporting element connecting said auxiliary weight to said gate, the connection of said supporting element to the gate being horizontally spaced from the plane of the gate, and a flexible second supporting element connected to said auxiliary weight and to said housing and of such length as to support the auxiliary weight when the gate from said closed position opens outwardly due to an outdraft.

4. In a draft regulator, a gate housing provided with vertical parallel inwardly projecting side plates having aligned horizontally elongated openings therein, a control gate disposed in said housing for pivotal swinging movement between said side plates, a pivot member mounted on said gate to project through said openings in said side plates and having knife-like pivot edges, V-shaped bearing members having disposed upon the bottom edges of said openings with the slots of the forward ends of the bearing members engaging the forward edge of the openings in said side plates, and bearing retaining plates mounted on said side plates to engage the slots in the rear ends of said bearing members whereby the bearing members are retained and rockably supported.

5. In a draft regulator, a gate housing provided with vertical parallel inwardly projecting side plates having aligned horizontally elongated openings therein, a control gate disposed in said housing for pivotal swinging movement between said side plates, a pivot member mounted. on

: said gate to project through said openings in V-shaped bearing members having slotted ends disposed upon the bottom edges of said openings with the slots of the forward ends of the bearing members engaging the forthe openings in said side plates, and bearing retaining plates mounted on said side plates to engage the slots in the rear ends of said bearing members whereby the bearing members are retained and rockably supported.

6. In a draft regulator, a gate housing provided with vertical inwardly projecting bearing supports having aligned openings therein, a control gate disposed for pivotal swinging movement in said housing, a pivot member mounted on said said supports, angled bearing members having slotted ends disposed upon the bottom edges of said openings with the slots of the forward ends of the bearing members engaging the forward edge of the openings in said supports, and bearing retaining members mounted on said supports to engage the slots in the rear ends of said bearing members whereby the bearing members are retained and rockably supported.
